PRE-heat Inc. provides custom designed and manufactured industrial air to air heat recovery equipment and systems for a variety of industries. We were contracted by a customer in the carbon fiber manufacturing industry to fabricate cooling tower heat exchangers to be used to cool hot air leaving a thermal fume incinerator. PRE-Heat Model V13/31-72-85.5-2S was manufactured using stainless and carbon steel to the customer's specifications. The system including a 2 shell pass, and vertical shell and tube heat exchanger installed in series for the hot air stream, and separate cooling air circuits. The air volume and temperature features included cool 6,300 SCFM, 1,600ᵒF to 1,750ᵒF hot air leaving a thermal fume incinerator cooled to 350ᵒF. It then entered a bag-house filtration system for final cleaning, and a cooling air stream for each exchanger that is 33,000 SCFM of 100ᵒF outside air. Auxiliary equipment consisted of two top hot air inlet plenums with internal insulation and an access door for cleaning, as well as two bottom outlet plenums with drains and access doors for cleaning.

This comprehensive customized system met the customer's specifications, and was delivered to Tennessee on time and on budget. For more information on how PRE-heat Inc. can manufacture a custom heat exchanger for your application, contact us.
